Study Notes
Classification of Computers
- Classification is based on system performance, which influences physical size and cost.
Categories of Computers
- Classification ranges from supercomputers (largest and most powerful) to microcomputers (personal computers).
- Categories include: Supercomputers, Mainframes, Minicomputers, Microcomputers (PCs).
Supercomputers
- Examples include Cray T3E-900 and GRAPE-4, recognized as the largest and fastest computers.
- Primarily used for scientific simulations, research in energy, space exploration, medicine, and industry.
- Considered the most expensive computers, often costing millions of dollars.
- Frequently found in organizations like NASA.
Monsters
- "Monsters" refers to custom-built supercomputers that require specialized technical teams for maintenance.
Mainframe Computers
- Very large, powerful, and expensive, serving as tailored systems for larger organizations.
- Offers faster processing speeds and greater storage than minicomputers, supporting over a hundred users simultaneously.
- Commonly utilized in banks, insurance companies, and corporations.
Minicomputers
- Became outdated, popular in the 1960s with capabilities between PCs and mainframes.
- Used primarily in small manufacturing plants and research labs.
- Allowed multiple users to share processing needs through terminals, with systems mass-produced in factories.
Terminals
- Terminals in minicomputers enable shared access to hardware by users.
- Typically consist of a keyboard, display screen, and connection wire to the computer system.
Microcomputers (Personal Computers)
- Also known as PCs, designed for individual use, available in various designs and forms.
- Include components such as a system unit, keyboard, mouse, and display screen, executing multiple tasks.
- Mass-produced with options for customization in software and hardware.
Types of PCs
- PCs classified based on size and cost include:
- Desktop
- Notebook
- Laptop
- Netbook
- Tablet
- Palmtop
Desktop Computers
- Designed for regular use at a designated location, typically near a desk.
- Common configuration includes power supply case housing motherboard, CPU, storage, keyboard, mouse, monitor, and speakers.
Motherboard
- A printed circuit board containing the CPU, memory, bus, and other essential electronic components.
Disk Storage
- Typically comprises hard disk drives, optical disc drives, and older models may include floppy disk drives.
Laptop Computers
- Portable computers with a flat display screen, weighing between 1 to 4 kilograms.
- Include notable types such as notebooks and sub-notebooks.
Notebook Computers
- A portable type of laptop weighing 2 to 4 kilograms with a size comparable to a thick notebook.
- Features a large color screen and keyboard, with touch-sensitive pads serving as mice.
- Easily transportable, utilizing electric outlets or rechargeable batteries, and can offer similar power to desktops but typically at higher costs.
